Which is better, Cellucor COR-Performance or BSN Syntha-6?

Cellucor COR-Performance wins on raw protein per scoop (25 g vs 22 g) and per-dollar value. BSN Syntha-6 wins on taste, slow-digesting profile and bedtime use thanks to its added casein. If you train hard and care about pure macros, go Cellucor. If you want a flavorful snack-replacement shake, go Syntha-6.

Are Cellucor and BSN owned by the same company?

Yes. Both Cellucor and BSN are owned by Glanbia Performance Nutrition, the same parent company that owns Optimum Nutrition and Isopure. The brands run independently but share manufacturing standards and ingredient sourcing. This is why you will often see both available at the same retailers (GNC, Walmart, Amazon, Bodybuilding.com) and at similar price tiers.

Does Syntha-6 have too much sugar?

Syntha-6 contains 3 g of sugar and 14 g of total carbs per 47 g serving. That is moderate for a meal-replacement style protein but high relative to a pure whey isolate. Syntha-6 Edge is the lower-sugar variant (2 g sugar, 24 g protein, fewer carbs). If you are cutting, Edge or Cellucor's COR-Performance Isolate fits better than the original Syntha-6.

Is COR-Performance Whey a true isolate?

No. COR-Performance Whey is a whey-blend product with whey protein concentrate as the primary ingredient and whey isolate as a secondary. Cellucor sells a separate COR-Performance Isolate product for shoppers who specifically want isolate-led macros. The 5 lb COR-Performance Isolate runs $54.99 at GNC with 30 g protein, 0 g fat per 34 g scoop.

Where can I buy both brands cheapest?

Walmart routinely undercuts on both brands. We track Cellucor COR-Performance 4 lb at $39.99 on Walmart and BSN Syntha-6 5 lb at $49.99. Amazon and Bodybuilding.com price-match within $2-3. GNC tends to be 15-25% more expensive at list but runs frequent BOGO 50% off promotions on house-affiliated brands (which includes both Cellucor and BSN).

Which has better flavors?

BSN Syntha-6 is widely regarded as one of the best-tasting proteins on the market. Cold Stone Creamery limited-edition flavors (Strawberry Banana Smoothie, Mint Mint Chocolate Chip) regularly top flavor blind-tests. Cellucor COR-Performance is competent (Whipped Vanilla and Peanut Butter Marshmallow are standouts) but not in Syntha-6's league. If flavor is your number-one criterion, BSN wins clearly.
